Definitions

  • the invention relates to a roller shutter for a roof window comprising an apron with practically horizontal displacement and formed of blades, the lateral ends of which slide in lateral guide rails located in the extension of a box secured to the sleeping frame of the rolling shutter and containing an apron winding and / or unwinding shaft and a drive shaft arranged downstream with respect to the winding and / or unwinding shaft and provided at each of its lateral ends with a cam wheel having an empty stroke appropriate to the variable pitch separating two gripping pins from two consecutive blades of the deck.
  • EP-A-0 145 628 already discloses a rolling shutter for a roof window comprising an apron with practically horizontal displacement and formed of blades whose lateral ends slide in lateral guide rails located in the extension of a box secured to the sleeping frame of the roller shutter and containing a winding and / or unwinding shaft of the deck and a drive shaft arranged downstream relative to the winding and / or unwinding shaft and provided with each of its lateral ends of a cam wheel having an idling stroke suitable for the variable pitch separating two gripping pins of two consecutive blades of the deck.
  • the bottom of the box is connected to the guide rails by a ramp on which slide the blades of the deck winding from the bottom up on the winding and / or unwinding shaft, the contact generator being located at the lower part of this tree.
  • this roller shutter cannot be used for roof windows comprising an opening that swings around a horizontal axis. Indeed, to allow the winding of the deck, it is necessary to raise relative to the guide rails the longitudinal central axis of the winding shaft, which gives the box a relatively large height.
  • the roof windows have a dormant frame projecting from the top of the roof covering which already constitutes an obstacle for the flow of water and / or snow.
  • a second obstacle consisting of a box of relatively large height, which increases the disadvantage of the defective flow of water and / or snow.
  • the present invention aims to remedy these drawbacks.
  • the invention as characterized in the claims, solves the problem of creating a rolling shutter for a roof window comprising, disposed beyond the upper edge of the upper cross member of the sleeping frame of the roof window, a box having a bottom located below the top of said sleeping frame and pivoting about an axis of rotation, located at the lower corner of its upper end and placed upstream of the winding and / or unwinding shaft, and containing forced guide means, interposed between the winding and / or unwinding shaft and the drive shaft, involving on the deck, between these two shafts, a reversal of the direction of winding of the deck on the shaft winding and / or unwinding, and a sleeping frame, connected by lugs to the side members of the sleeping frame of the roof window and provided with damping means located at the lower end of the lateral guide rails.
  • the advantages obtained thanks to this invention essentially consist in providing the roof window with a rolling shutter whose height of the projecting part of the box relative to the top of the sleeping frame of the roof window is reduced. Therefore, a significant stagnation of water and / or snow is avoided above the upper edge of the roof window provided with the roller shutter. Furthermore, the damping means balancing either the weight of the roller shutter alone, or the sum of the weight of the latter and the weight of the window opening frame make it possible to avoid a sudden lowering, in particular of the roller shutter during rotation around its axis of articulation.
  • An advantageous embodiment of the invention provides that the forced guide means comprise two lateral guides cooperating with the lateral ends of the blades of the deck provided with the gripping pins.
  • the lateral guides comprise an upward curvilinear sector partially coating the cam wheels of the drive shaft. This increases the engagement between the blades and the cam wheels.
  • Another application of the invention is obtained by a design providing that the gripping pins slide on a support ramp of the lateral guides annihilating any bending of the gripping pins.
  • the gripping pins have a resistance which may be greater than the torque of the motor of the drive shaft.
  • the gripping pins cause the motor to slip and the drive shaft to stop. As a result, the deck remains stationary.
  • a window 1 essentially composed of a sleeping frame 2 and an opening 76 tilting about an axis of horizontal rotation 3.
  • the present invention essentially relates to roof windows projecting from the top 4 of the roof covering.
  • this roof window 1 is provided with a rolling shutter 5.
  • This consists of a sleeping frame 6 resting on top 7 of the sleeping frame 2 of the window 1 and an apron 8 formed of parallel blades 9, 10, 11.
  • the lateral ends 12 of the blades 9, 10. 11 slide in lateral guide rails 13 whose lower ends (not shown) are interconnected by a cross member serving as a stop for the deck 8.
  • the upper ends 14 of these guide rails 13 terminate at the inlet 15 of a box 16.
  • said box 16 necessarily has a height 17 slightly greater than the winding diameter 18 of the rolled up apron 8 to have a free space for the passage of foreign objects such as leaves, pebble or the like which could have been entrained inside the box 16 despite the presence of a brush 19 located at the entrance 15 of said box 16.
  • the protrusion above the sleeping frame 2 of the roof window 1 is as low as possible to avoid excessive stagnation of the water and / or snow located upstream of the caisson 16.
  • the box 16 has a bottom wall 25 located in the extension of the bottom wing 22 of the lateral guide rails 13 connected to the bottom 21 by an inclined face 26.
  • the longitudinal members 28 of the fixed frame 2 of the roof window 1 of the roof window 1 are fixed with two tabs 29 between which the box 16 is disposed.
  • the roller shutter 5 is made integral with the sleeping frame 2 of the roof window 1.
  • this axis of rotation 30 also serving as a connection between the box 16 and the legs 29, is located in the lower corner 31 of the upper end 32 of the box 16. This particular position of the axis of rotation 30 allows the rolling shutter 5 to be raised and / or lowered.
  • this axis of rotation 30 is a hinge axis passing right through the box 16 and the ends 33 of which are housed in bearings 34 integral with the lugs 29.
  • this axis of rotation 30 consists of two ends of axes projecting outwardly relative to the side walls 35 of the box 16 and engaging in bearings 34.
  • the central part located between the two side walls 35 would be free of any obstacle against which the deck 8 could abut.
  • the means used for winding and / or unwinding the deck 8 are the same as those used for the roller shutters whose deck moves almost horizontally.
  • the box 16 contains a shaft 36 for winding and / or unwinding the deck 8 and a drive shaft 37.
  • This drive shaft 37 is parallel to the winding shaft 36 and is located downstream with respect to to the latter.
  • Said drive shaft 37 is integral in rotation with an electric motor (not shown).
  • Each lateral end 38 of the drive shaft 37 is provided with a cam wheel 39 having, between the different branches 40, 41, 42 forming a star, an idle stroke. These cam wheels 39 cooperate, for driving the bulkhead 8, with gripping means formed by pins 43, 44. 45 projecting with respect to the lateral ends 12 of the blades 9, 10, 11.
  • the apron 8 passes under the drive shaft 37.
  • the deck 8 sliding along the bottom wall 25 of the box 16 to be raised towards the top wall 46 of the box 16 and is wound on the winding and / or unwinding shaft 36 from high to low.
  • the latter may include an opening allowing the evacuation of foreign bodies, this opening being able to be constantly open or can be closed by a movable cover. To this end, it is therefore necessary for the deck 8 to pass over the winding and / or unwinding shaft 36 and to modify the direction of movement of the deck 8 because it passes under the drive shaft 37 .
  • the invention provides for forced guide means 49.
  • These forced guide means are arranged between the winding and / or unwinding shaft 36 and the drive shaft 37 and consist of two lateral guides. 50.
  • These lateral guides 50 comprise a straight segment 51 parallel to the lower wall 25 of the box 16. This straight segment 51 leads to an ascending curvilinear sector 52. The latter involves in the deck 8 an upward movement so that the latter winds up partially around the cam wheels 39.
  • several gripping pins 43, 44, 45 are brought into contact with several branches 41, 42 of the cam wheels 39, which makes it possible to increase the driving force of the bulkhead 8.
  • the different branches 40, 41, 42 of the cam wheels 39 move inside a groove 53 produced in the lateral guides 50.
  • This groove 53 is located, in the transverse plane of the lateral guides 50, between a support ramp 54 and a bearing 55. On the support ramp 54 slide the gripping pins 43, 44, 45 while on the bearing 55 slides the underside 56 of the blades 9, 10, 11.
  • pressure means 57 are provided on the drive shaft 37.
  • these pressing means 57 are an elastic jacket threaded onto the drive shaft 37, this elastic jacket, integral in rotation with the latter, exerting pressure on the top 47 of the deck 8.
  • these pressing means 57 are elastic flanges disposed at the lateral ends 38 of the drive shaft 37, these flanges, integral in rotation with the drive shaft 37, can be attached to the wheels with cams 39.
  • this resistance will be greater than the torque of the electric motor actuating the drive shaft 37.
  • roller shutter 5 is provided with damping means 60. These are located in each lower end 61 guide rails 13 and are intended to balance and compensate for the weight of the shutter 5 after rotation about the axis of rotation 30. Thus, the shutter 5 retains its position conferred by the user. To lower said rolling shutter 5, the user must voluntarily exert traction.
  • damping means 60 are constituted by a carriage 62 comprising rollers 63, 64 sliding in a housing 65 arranged in each lower end 61 of the two guide rails 13.
  • the upper end 66 of the carriages 62 is integral with the end 67 of an elastic element 68, the other end 69 of which is integral with a stop 70 fixed to the guide rails 13.
  • This carriage 62 has at its lower end 71 a control finger 72 cooperating with a roller 73 pivoting around an axis 74 secured to the lower end 75 of the tilting opening 76 of the window 1.
  • the elastic element 68 When the roller shutter 5 is in the folded position and rests on the sleeping frame 2 of the roof window 1, the elastic element 68 is under tension.
  • the distance between the axis 74 of the roller 73 and the lower end 61 of the guide rails 13 tends to increase due to the difference in the arcs of the circle 77, 78 described one by the axis 74 relative to the horizontal axis of rotation 3 of the tilting opening 76 and the other by the lower end 61 of the guide rails 13 relative to the axis of rotation 30
  • Due to the action of the tensioned elastic element 68 the control finger 72 remains in contact with the roller 73 and the carriage 62 slides in the direction of the stop 70. During this course of the carriage 62, the tension of elastic element 68 decreases and it takes its rest position as it opens.
  • the expected force of the latter can be a function of the weight of the rolling shutter 5 to balance the latter, but one can also provide an elastic element 68 having a force balancing not only the weight of the rolling shutter 5 but also that of the tilting opening 76 .
